A horizontal footbridge of uniform density has a length of $12\,\text{m}$ and a weight of $4000\,\text{N}$. It is supported at two points, X and Y, as illustrated. A man whose weight is $600\,\text{N}$ stands $4\,\text{m}$ from support X. What upward force does support X exert on the footbridge?
- A$2200\,\text{N}$
- B$2300\,\text{N}$
- C$2400\,\text{N}$
- D$2600\,\text{N}$
